Experts say temperature will drop 30 degrees by end of week

Truckee and most of the western United States has enjoyed summer-like temperatures and clear, sunny days lately – but a drastic shift may come this week.

“It looks like things are going to change, and quickly. It’s going to change from summer to winter,” said Jim Ashby, a climatologist for the Western Region Climate Center in Reno.

“We’ve just been stuck in a high pressure system,” he said. “The entire western half of the United States is in a high pressure area. For whatever reason you get these high pressure areas.” High pressure areas create the warm temperatures.

Truckee’s high temperatures throughout October have been close to records, but no official numbers have been released by the Climate Center. The temperatures have, however, been running well above average. According to the center, the average high for Truckee in October is 63.7 degrees.

Oct. 9, 1996 brought Truckee its highest October temperature, with a sunny 87-degree day. For this week, the high was 77 degrees, recorded on Oct. 28, 1968. On the other end of the spectrum, Truckee’s low was 7 degrees on Oct. 29, 1990.

Although the sun has lingered, Ashby said the weather is expected to change quickly, once the high pressure system breaks down. Ashby said the changes should come in the next few days.

“It should drop 30 (degrees) by the end of the week,” he said.

Snow is also on the horizon. There is a chance it could fall on Thursday or Friday, Ashby said. According to the Weather Channel’s Web site, Truckee could see rain and/or snow showers on Friday and Saturday, and a few snow showers Monday, Nov. 3.

Mark Dinger, a spokesman for Caltrans District 3, said chains are usually required if the snow sticks and a crust starts to form. The decision is made on the spot, and Dinger said, “It’s always a good idea to have chains with you.”

Dinger said Caltrans is already preparing for the winter and is “keeping a close eye on the forecast.”

In addition, Ashby and the Weather Channel both say the lows for Truckee will drop into the teens later this week through early next week.

The Weather Channel reported the top-five highest temperatures for Monday were all in California.

Don Rogers: That sieve, memory


An older friend I made when I began here in 2016 called the other day to talk about the paper. I hadn’t heard from her in awhile and, well, I’ve been here just long enough…
